In recent study on design of experiments, the complicate metamodeling has been studied because defining exact model using computer simulation is expensive and time consuming. Thus, some designers often use approximate models, which express the relation between some inputs and outputs. In this paper, we review and compare the complicate metamodels, which are expressed by the interaction of various data through trying many physical experiments and running a computer simulation. The prediction model in this paper employs interpolation schemes known as ordinary kriging developed in the fields of spatial statistics and kriging in Design and Analysis of Computer Experiments (DACE) model. We will focus on describing the definitions, the prediction functions and the algorithms of two kriging methods, and assess the error measures of those by using some validation methods.

The architectural design of student circulation space has a pronounced influence on the educational function of a school building. Recent curriculum and new teaching methods have required the sufficient space provided for circulation and various circulation spaces in a school building, such as elevator, pilotis, bridge, atrium, deck, lobby and locker room. However excessive circulation space is wasteful form the standpoint of both initial investment and operation. This study aims to investigate new circulation patterns and functions, and to propose the adequate size in planning a school corridor. For this purpose, it explores the recent trends of the corridor planning represented in the excellent school facilities in 2002. and analyzes the newly-added functions In the school corridor : architectural in-between space, dwelling space for ordinary activities, space for educational media and auxiliary learning space. This research recommends that the corridor width be carefully planned according to the supposed functions in order to achieve the efficiency in the design of school facilities.

Computers have become an indispensable part of everyday lives in 21st century. This is particularly true in early childhood education; multimedia use in kindergarten has rapidly grown in the last decade. Although ample research had been done on the issues of teachers' role in multimedia settings and selecting quality materials, few studies have been done on the proper environment for multimedia use in early childhood education. In this regard, this research examines the current status of multimedia use-animated illustration films, CD-ROM titles, and internet-in kindergarten. In addition, computer environment in kindergarten is investigated in order to provide guidelines for appropriate facilities and equipments. For smooth integration of computer activities into a school system, computers are located in ordinary classrooms in more than half of kindergarten in Seoul. Computers are used in independent lab settings in the last of the kindergarten in Seoul and there are four different types of lab settings. Among them computer at perimeter style is preferred for the ease of student-teacher, and student-student interactions. The importance of environment for early childhood education cannot be overestimated. It is so critical for early childhood education that the people in this field regard the environment as 'the third teacher' next to parents and teachers. Therefore the multimedia environment should also be considered seriously for the maximum use in early childhood institutions.

The collected materials were investigated in quality and content. As for the data, five Contemporary folk Hanbok brands, in the city were selected and twenty styles from catalog were extracted. The subjected of study were 219 university students living in Seoul and Kwang-ju, Mok-po. they answered the questionnaires, the results of study were following: 1) In style of Contemporary folk Hanbok, there were positive support on longer Jeogori than traditional one and a seamless one-piece skirt at the length of ankle. But they had the negative thought of various spapes shapes related to the styles of Contemporary folk Hanbok. 2) In a view point of coloring on women's Contemporary folk Hanbok, the student supported the saturation more than special preference to similarity or contrast harmony. Students liked the harmony of achromatic colors or same colors up and down which are not traditional 3) In men's Contemporary folk Hanbok, students were for the harmony of same colors in up and down, preferring wool/polyester to cotton or silk100% (traditional materials) in materials 4) It indicates that what students thought generally of the occasional appropriateness of Contemporary folk Hanbok didn't match with the choice of proper occasion on preferred style. The western clothes have difference in design, material, color and manners of co-ordination related to ordinary cloths and out wear, but Contemporary folk Hanbok don't have these difference. Therefore, it is needed to develop the expensive designs discriminated between ordinary clothes and out wear in design, material, color and co-ordination corresponding to the every day life style.
